Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in winter, providing just enough to prevent the soil from becoming bone dry.

Avoid overwatering, as this can lead to root rot. Ensure good drainage.

Prune to maintain shape and remove any dead or damaged stems. Pinching back young plants can encourage bushier growth.

Minimal pruning is usually required; focus on removing spent flower stalks to prevent self-seeding if unwanted, and tidy up the plant's appearance.

Propagate by seeds sown in spring, either directly outdoors after the last frost or started indoors a few weeks prior. Seeds germinate best with light stratification and warm temperatures.

Cuttings can also be taken in late spring or early summer.

Repotting is typically only necessary for container-grown plants when they become root-bound. This is usually done in early spring before new growth begins. Use a well-draining potting mix and a pot with drainage holes.

Avoid disturbing the roots excessively.
